It is impossible to say, from the single example before me, 
whether the markings on the elytra of this species are constant ; 
it is probable that one or other of them may be entirely obli- 
terated ; at all events, the species, whatever may be the degree 
of markings, is amply different from all others of this paper. 
The peculiar markings of the thorax (very much resembling 
those of P. guttata, Fab.) and the almost obsolete punctures on 
the elytra sufficiently distinguish it. 
A single specimen from the Cape, taken by Drégé, I received 
in M. Chevrolat’s collection.

The above description is Se on two specimens—one from 
the collection of Mr. Baly, and one which I received from M. 
Chevrolat. The species differs entirely from P.24-signata, Thunb., 
both in punctuation, in arrangement of the three transverse 
rows of macule, and also in the colour of the thorax. I can 
conceive that in its maculations the species may be subject to 
some variation. 
This is the only species known to me that agrees with the 
short description given by Fabricius (Ent. Syst. Supp. 86. 26 ; 
Syst. El. 1. 432) of P. ebroéa. I have no means, however, of 
verifying it. 
From the Cape of Good Hope.
